PCTA Copolyester. Poly(l,4-cyclohexanedimethylene terephthalic acid) (PCTA) copolyester is a polymer of cyclohexanedimethanol and terephthalic acid, with another acid substituted for a portion of the terephthalic acid otherwise required. It has the following formula ... [Pg.1020]

Brink, A. E., Turner, S. R. and Keep, G. T Poly(alkylene ether)s as plasticizers and flow aids in poly(l,4-cyclohexanedimethylene terephthalate) resins, US Patent 5 965 648, 1999. [Pg.559]

Cyclohexanedimethylene Terephthalate/PTME Terephthalate Copolymers. Poly ether-ester copolymers based on 1,4-cyclohexanedi-methanol have been prepared using both frans-1,4-cyclohexanedimethanol (f-CD) and a practical grade of 1,4-cyclohexanedimethanol (p-CD) which is reported to contain about a 68/32 mixture of trans- to cis-1,4-cyclohexanedimethanol (26), Gas-phase chromatography of one of our samples of p-CD indicated a 72/28 ratio of trans-to-cis isomer. By use... [Pg.142]

Chemiluminescence processes in thermal and photochemically oxidised poly (ethylene - co - 1,4- cyclohexanedimethylene terephthalate). N. S. Norman, S. Allen, G. Guillaume Rivalle, M. Mchele Edge, T. Teresa Corrales, F. Fernando Catalina/ZPoZjroer degradation and stability (2002), 75, 2, 237 - 246. [Pg.171]

Poly(ethylene-co-1,4-cyclohexane dimethylene terephthalate) The thermal and photochemical oxidation processes of a polyester based on poly(ethylene-co-l,4-cyclohexanedimethylene terephthalate) (PECT) with approximately 30% of 1,4-cyclohexanedimethanol have been studied by means of chemiluminescence [88], Also, the stabilization activity of some commercial antioxidants has been evaluated, and it has been related to hydroperoxide levels in the polymer. [Pg.119]

The preferred synthesis route for these copolymers is transesterification. There are two steps in the preparation of poly(ethylene-l,4-cyclohexanedimethylene arylate) (PECA). [Pg.261]

Studies have been carried out on the UV degradation of poly(ethylene-co-l,4-cyclohexanedimethylene terephthalate) [35,38,56]. The PET sections of the chain will undergo the various initiation, abstraction and oxidation processes already considered, but a tertiary hydrogen on the cyclohexane ring of the poly(l,4-cyclohexanedimethylene terephthalate) units means that formation of tertiary alkyl radicals and subsequent autoxidation at this site will predominate over formation of secondary alkyl radicals on methylene units or elsewhere... [Pg.93]

Stabilisers of this type have been claimed as extremely effective UV absorbers for poly(ethylene-co-l,4-cyclohexanedimethylene terephthalate) [98-100], allowing the use of this material in outdoor applications. Developments in novel synthesis methods have improved the inherent stability of this class of additive, paving the way towards their more effective use in aromatic polyesters [101-106]... [Pg.210]
